by the mining process. A metal slope belt drive building with dimensions of 32' x 40' x 20', located north of the <br />existing transfer building was constructed in 1995 and provides electrical and mechanical support for conveyor <br />system. Bonding calculations addressing removal of the new slope belt drive building are presented in Volume 1- <br />A. <br />Feeders onto the belts located in the reclaim tunnels feed coal from the stockpile. The overland belt was <br />constructed during 1989, and it conveys coal from the reclaim tunnel to Tipple 2.. If trucks were used for coal <br />haulage the coal would be loaded out of the stockpile with a loader or similar type of equipment and hauled to <br />Tipple 2. This would only occur in the case of an emergency. <br />TCC's upgraded coal handling facility provides the mine an opportunity to convey coal at varying rates depending <br />upon demand. Construction practices will include driving/installing caissons, building grade beams and footers to <br />provide an adequate foundation for the various structures. The individual design requirements of the various <br />structures dictates the type of foundation. The facilities aze shown on Map 24. <br />During the upgrade the slope conveyor belt was increased in size to accommodate the higher tonnage. All of the <br />belts and systems are sized to efficiently convey the increased tonnage. The existing transfer building issued to <br />support the slope belt. <br />The new transfer building is located south of the existing transfer building. In this building coal will be transferred <br />from the slope belt to the stacker tube feed belt, or waste rock will be transferred from the slope belt to the waste <br />rock conveyor belt. The location of the belt has been modified to facilitate operations around the storage building. <br />The new location, as shown on Map 24, Surface Facilities, requires excavating approximately 11,000 CY of spoil <br />and rerouting ditch D-4 around the stockpile. The excavated material was either placed in the reclaim tunnel <br />excavation or in the waste rock disposal area. The excavated spoil was be sloped to a ]h:lv or steeper depending <br />• upon field conditions. If field conditions require, a safety bench will be constructed in the cut slope. Removal of <br />this material will not impact the reclamation plan. <br />A 16 ft. by 38 ft. roofed shed addition was added to the south wall of the existing transfer building in October <br />2003. This addition is supported by five piles 10" x 57' driven to approximately 30'. The piles aze all constructed <br />with concrete pile caps having concrete piers above them. This building will be used to cover the rock belt and <br />include a wash sump. <br />A propane heater system was installed on a 20 ft. by 20 ft. 2-ft. thick concrete pad adjacent to the existing transfer <br />building (northeast side) in October 2003. The heating system will be used to heat the transfer building, adjacent <br />sampling building, and replace the existing heating line to the portal. The heater system consists of a <br />polypropylene 2-inch vapor propane feed line. The line running from the existing 18,000 gallon propane tank on <br />the surface is approximately 700 feet in length. The line is buried at a depth of approximately 4-feet from the <br />existing propane tank to the new concrete pad location. The line is 2-inch schedule 40 steel and is supported and <br />anchored at the point where it goes over the high wall. A vaporizer, and 6 ft. by Eft. by Eft. concrete pad at the <br />tank location and a regulator at the heater location is included . <br />To protect the #4 bent on the TCC stacker conveyor, a steel revetment approximately 25' x 25' x 55' was <br />constructed on concrete footers. The revetment may have a roof to prevent the accumulation of coal inside the <br />revetment. The concrete footers will be pushed to the base of the portal highwall and be buried during final <br />reclamation activities. <br />During construction of the coal stockpile pad and the haul road a minor amount of cut and fill work was required. <br />The northwestern edge of the pad and the haulroad required approximately 20,000 CY of fill. The remainder of <br />• the azea was required approximately 6,000 CY of fill to get the pad to Bade. During the site preparation some of <br />the existing fill was cut from the site. the overall estimates indicate approximately 15,000 CY of material will be <br />PR 03-06 2.05-25~' 05/06/04 <br />
